Answer 1

Total cost of buying both items is $36.21.

Explanation:

We are given that a baseball cost $7 and a baseball bat cost $27.

Also, we are given a tax rate of 6.5%

Now, to find the total cost of both items we will find the individual costs of both items by applying tax rate on it.

Cost of baseball after applying tax rate is given by;

Since we know that by applying a tax on any item it's cost gets increased.

So, Cost of baseball after tax = Cost of baseball before tax + Amount of tax

Amount of tax = Tax rate
`*` Cost of baseball

= 6.5%
`*` $7

=
`(6.5)/(100) * 7` = $0.455

So, Cost of baseball after tax = $7 + $0.455 = $7.455

Cost of baseball bat after applying tax rate is given by;

Cost of baseball bat after tax = Cost of baseball bat before tax + Amount of tax

Amount of tax = Tax rate
`*` Cost of baseball bat

= 6.5%
`*` $27

=
`(6.5)/(100) * 27` = $1.755

So, Cost of baseball bat after tax = $27 + $1.755 = $28.755

Now, the total cost of buying both items = Cost of baseball after tax + Cost of baseball bat after tax

= $7.455 + $28.755 = $36.21

Therefore, the total cost of buying both items is $36.21.
